Bilateral discoid medial menisci with extensive intrasubstance cleavage tears: MRI and arthroscopic correlation
1Ohio State University Sports Medicine Center, Columbus 43221.
Abstract:
Although rare, the discoid meniscus can become problematic in active individuals. The arthroscopist is then presented with a challenging treatment problem. Through the current techniques of arthroscopy and MRI, the diagnostic and treatment difficulties are lessened; however, our understanding of the discoid meniscus is incomplete. Currently, the need exists for correlation between arthroscopy and MRI. We present a case of bilateral complete discoid medial menisci with symptomatic extensive intrasubstance horizontal cleavage tears. Both arthroscopy and MRI views of the lesions, pre- and postoperative, are presented. A review and discussion of the literature is included.
Insights
Discoid meniscus tears can challenge active individuals. This case highlights the need for correlating arthroscopy and MRI findings for better diagnosis and treatment of these rare knee injuries.
Area of Science:
- Orthopedics
- Sports Medicine
- Radiology
Background:
- Discoid meniscus, a rare congenital anomaly, can cause knee pain and injury in active individuals.
- Current diagnostic tools like arthroscopy and MRI have improved understanding but gaps remain.
- Correlation between arthroscopic and MRI findings for discoid meniscus is often incomplete.
